Can a motor spin without magnets? It sounds like a trick question. For decades, the industrial world has relied on magnets—either permanent or electromagnetic—to drive the motors that power our factories.
But ABB has just shattered that rule.
With the launch of the world’s first magnet-free IE6 SynRM motor certified for hazardous areas (ATEX/IECEx), the game has changed. If you are running an industrial plant in Lahore, Karachi, or anywhere in Pakistan, this “mystery” technology could be the key to slashing your skyrocketing energy bills.
1. What is a Magnet-Free Motor?
The technology is called Synchronous Reluctance (SynRM).
In a traditional motor, magnets “pull” the rotor to make it turn. In a SynRM motor, the rotor is made of specifically cut steel laminations. It uses a principle called magnetic reluctance—the rotor naturally wants to align with the magnetic field produced by the stator.
The Result: It spins with incredible precision, but without the heat or the cost associated with magnets.
2. Why “Magnet-Free” is Better for Your Factory
Using magnets has hidden costs. Permanent magnets use rare-earth metals that are expensive and heat-sensitive.
- Cooler Operation: Since there is no current flowing through the rotor and no magnets, the motor runs much cooler.
- Longer Bearing Life: Heat is the #1 killer of motor bearings. Cooler motors mean your equipment lasts years longer before needing a repair.
- No Demagnetization: In high-heat industrial environments, magnets can lose their strength over time. SynRM motors don’t have that risk.
3. IE6: The New King of Efficiency
Most factories in Pakistan currently use IE2 or IE3 motors. ABB’s new motor is IE6 “Hyper Efficiency.”
How big is the difference?
ABB reports that this motor has 60% lower energy losses than a standard IE3 motor.
In a country where industrial electricity tariffs are rising, a 60% reduction in motor energy loss isn’t just an “upgrade”—it’s a survival strategy.
4. Safety in Hazardous Zones (ATEX/IECEx)
One of the most impressive parts of this announcement is the certification. This motor is designed for Zones 1 and 2.
- Oil & Gas
- Chemical Plants
- Pharmaceutical Manufacturing
- Food & Beverage
In these areas, a sparking motor or an overheating rotor is a catastrophe. The IE6 SynRM’s cool-running design makes it the safest choice for explosive environments.
5. The “Catch”: You Need a Brain (VFD)
You cannot run a magnet-free SynRM motor by simply plugging it into the wall. It requires a Variable Speed Drive (VFD) to control the magnetic field.
This is where many businesses in Pakistan struggle. Installing a high-tech motor without the right drive configuration is like buying a Ferrari and putting a tractor engine in it. To get the 60% energy savings, your VFD must be programmed and calibrated perfectly.
